Abstract
In a gear for the transmission and/or transformation of the changing or alternating rotary movement of a drive, a cam plate is associated with the latter and has a guidance channel for receiving the said driver. The driver rotates in a radius about a center, a further driver being connected to said center and engages in at least one reception groove of the cam plate, when the first driver is disengaged from the guidance channel.
Claims8
A gear for transforming or transmitting alternating rotary movement of a drive into linear movement which comprises:
- a first driver which rotates in a first radius about a center;
- a cam plate having a guidance channel for receiving the first driver and at least one reception groove;
- a second driver which rotates in a second radius about said center;
- said second driver engaging said at least one reception groove when the first driver is disengaged from said guidance channel and each said reception groove has an axis with a radius about a center point which corresponds to said second radius, whereby said cam plate moves linearly along a first axis as said first driver is rotated about said center and moves along said guidance channel.
